CUTLERY-POLISHING MACHINE.

SPECIFICATION forming' part of Letters Patent No. 662,919, dated December 4, 190.

Serial No. 554,903. (No model.)

county and State of New York, have invented a certain new and useful Cutlery-Polishing Machine, of which the following is a specification.

Our invention relates to a cleaning and polishing machine adapted for use primarily for renovating articles of small size, as knives, forks, dac., or other cutleryware, and has for its object the provision of a machine of the class described simple in construction, inexpensive in manufacture, and efficient in practical use.

To attain the desired end, ourinvention consists in the construction, arrangement, and operation of parts hereinafter set forth.

Figure l represents a plan view of a machine constructed according to our invention. Fig. 2 is a vertical transverse section of the same, taken on the line 2 2, Fig. l. Fig. 3 isV a view of the bottom of our machine. Fig. 4 is a transverse section of our base or bed plate. Fig. 5 is a partial side elevation of the said base. Fig. 6 is an end View in detail of our machine, and Fig. 7 is a detail of our knife-rest.

Referring particularly to the drawings, A denotes the bed or base framework of our machine, which is provided with two high posts A' and three small posts A2 and with three front slots a c' a" and one rear slot a2. The base A also supports a central roller A3, which prevents the knife from being tilted. Mounted upon the base A is our roller-inclosing frame or shell B, provided upon the central portion of its rear and front faces with lugs b, which serve to adj ustably support by means of screws b2 the rotatable knife-rests B', provided with cushioned tops 4b', made of any suitable material, as of leather.

C represents our carriage, provided at one end with an adjusting screw C2, passing through an oriiice in the side of our bed A, and at the other with two posts C', located at opposite sides of the end C3 of our carriage, and also with a transverse extension C4, provided with a plate C6, resting on top of the bed A and connected with the carriage C by means of a flat post C7, working in a slot d" of the said bed A. rlhe plate C6 is provided with a bifurcated vertical portion C5. The posts C' rest and travel upon the top of our bed-plate A, the lower thinner portions of the said posts C', adjacent Vtot the carriage C, passing through thenarrowed parts of the slots ct' d2.

The posts A' support a horizontal shaft H, and the posts C' support a similar shaft H'. These shafts are provided with pins hand h', which lie in recesses of the hubs of the interchangeable disks L, secured together by screws L', located on both sides of our wheels J J' K K', constructed of tlexible or elastic material, as of rubber, the said hubs abutting or running against the journals formed by the posts A' and C'.

Our wheels J J' K K' are ordinarily faced with flexible material, as jj', preferably consisting of leather and ordinarily coated with emery, rottenstone, or any suitable cleaning or polishing powder.'

The front post A' carries two gear-wheels* namely,an upper gear-wheel Gr and a lower bevel-gear F, meshing into gear G-and the front post C' of the carriage C also carries two gear-wheels-namely, an upper gear Gr' and a lower bevel-gear F', meshing into the gear G'. A shaft D crosses the front of our machine, to be ont of the path of the knife, and is provided with an operating-handleD' and with a rigid bevel-gear E, which meshes with the bevel-gear F and also with a loose bevel-gear E', the hub of which works on the key CZ. The bevel-gear E meshes with the bevel-gear F' of the post C' and is held adjacent thereto by means of the bifurcated vertical 'extension C5 of the carriage C. The rest M is secured to the shell B by means of the screw m. A sectional buff or brush, consisting of the wide layers or disks N and narrow ones n, is carried by a shaft D2, which is providedwith a bevel-gear d2, which meshes with the bevel-gear d3 of the shaft D. The pawl g, adjacent to the bevel-gear G, prevents the parts from being turned the wrong wa Y.

A trough Q is secured to the bed A by a screw q2 and is provided with notches q, which serve as kniferests whereby to evenly grind knives when an emery-wheel is placed on the shaft D2.

IOO

. fact that the said tops are rotatable.

It is manifest lthat various omissions of some particulars could be made Without materially affecting the essential features of our invention or the operation of the remaining parts, and we do not therefore wish to be limited to the specific structural details of the organization herein set forth. Obviously the elements of the structure described may vbe located at an angle to the plane in which they are shown, or they may be inverted, if desired. We accordingly use the words vertical,V horizontal, and the like in a relativesense. A

In operation the article to be renovated, as the knife O, is placed between the wheels J J K K', (the rests B serving to keep the same level,) and upon turning the handle D and drawing theknife through the machine the same will be found to be cleaned and polished. The rests B may be raised or lowered, according to whether a wide or narrow knife is used, and any excessive wear of the leather tops of the same is avoided by the In cases where thin knives are to be cleaned the elastic wheels K K may be caused to approach the wheels J .J by manipulating the screw C2, the adjacent peripheries of the same becoming thereby flattened. The Wheels K K' will be operated in any position (contiguous or adjacent) by means of the handle D on account of the fact that the gears G', F', and E travel with the carriage C. When not in use,

the wheels K K may be drawn away from the wheels J JC Guards P P are used to cover the bevel-gear in order to prevent da nger of injury to the hand of the operator.

Forks, as T, may be polished by holding the same against the leather facing of our rubber wheels or tires by use of the rest M,A or the sectional buff' or brush N n may be used in order to clean the interior of the tines of the same. By resting the back of a knife in one of the notches q of the trough or cup Q the edge of the same may be ground against an emery-wheel R. v

As it is evident that many changes in the construction and relative arrangement of parts-might be resorted to without departing from the spirit and scope of our invention, we would have it understood that we do not restrict ourselves to the particular construc- What we claim as new, and desire to secure by Letters Patent, is-

l. In a cutlery-polishing machine; the following elements; shafts of two rotatable cleaning devices, means to move one shaft forward and backward (parallel to the other) and rigidly hold t-he same in any desired position; a main operating-shaft located below the plane of the two said shafts; and stationary and shifting means to similarly rotate the stationary and movable shafts in opposite direc-v tions whether the sameare moving forward or back or lying adjacent or apart; and detachable rotatory cleaning devices.

2. In acutlery-polishing machine, the following elements; shafts of two rotatable cleaning devices, one shaft mounted in a movable carriage constructed and arranged to contain the cleaning devices the other shaft being supported directly by the base of the machine; means to move one shaft forward and backward (parallel to the other) and rigidly hold the same in any desired position; stationary and shifting means to similarly rotate the stationary and movable shafts in opposite directions whether the same are moving forward or back or lying adjacent or apart; and detachable rotatory cleaning devices.

3. In a cutlery-polishing machine, the following elements; shafts of two rotatable cleaning devices, means to move one shaft forward and backward (parallel to the other), and rig idly hold the same in any desired position; stationary and shifting means to similarly rotate the stationary and movable shafts in opposite directions, whether the same are moving forward or back or lying adjacent or apart; detachable rotatory cleaning devices and means located above and intermediate of said shafts to support the article to be cleaned.

In testimony of the foregoing specification we do hereby sign the same, in the city of New York, county and State of New York, this 23d day of February, A. D. 1893.
